Description

Technical Field

[0001] The utility model relates to the field of servo driver installation, in particular to an AC servo driver end cover which is convenient to install. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] A servo drive is a controller used to control a servo motor. A circuit board is provided inside the servo drive, and the circuit board is connected to the display screen, wiring holes, connector ports, etc. When installing the end cover of the servo drive, it is necessary to fine-tune the positions of the display screen, wiring holes, connector ports, etc. so that they can be limited on the servo drive end cover. However, the adjustment of multiple components can only be done one by one. If one of them is wrong during the position adjustment, it will affect the installation of the remaining components. Therefore, how to facilitate the installation of the servo drive end cover when there are multiple components at one end of the end cover is a problem to be solved.

[0004] For most servo drive end covers, most of them are installed by first installing the servo drive end cover and leaving a large space at the position of the component. After the servo drive end cover is installed, the limiter is installed at the corresponding position to limit the display screen, etc. However, there are multiple positions on the servo drive end cover where the limiter needs to be installed, and it takes a lot of time to install them one by one. Therefore, how to facilitate the installation of multiple limiters is a problem to be solved. When there is a large error between the position of a limiter and the component to be limited, how to avoid the disassembly and reinstallation of the remaining limiters is a problem to be solved. That is, when a component is offset or tilted during installation, reducing the impact on the overall end cover is a problem to be solved.

[0005] In summary, how to facilitate the installation of the servo drive end cover is a problem to be solved, how to limit multiple components at the same time when installing the servo drive end cover is a problem to be solved, and how to reduce the impact on the whole when an error occurs in a component is a problem to be solved.

[0024] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0025] The utility model discloses an AC servo driver end cover that is easy to install. The main structure includes an end cover 1, and the end cover 1 is provided with a plurality of through holes 2. Since the servo driver needs to control the servo motor and connect the power supply, etc., the end cover 1 and the shell of the servo driver are arranged on the outside of the circuit board of the servo driver to protect the internal parts. In order to enable the servo driver to operate normally, the end cover 1 is provided with a plurality of through holes 2. The corresponding components on the circuit board inside the servo driver at the through holes 2 can be connected with the corresponding device, so as to achieve the function of controlling the servo driver. However, the servo driver end cover 1 is mainly divided into a display screen, a connector port, a connection hole and the like. In order to ensure the neatness of the connection position, that is, to avoid the influence of dust, etc., the connection hole is usually provided with an external protective shell. When the power supply and other lines need to be connected, the protective shell is opened so that the connection hole can be used normally. The position of the display screen and the connector port also needs to be sealed and clamped accordingly. That is, the display screen needs to be guaranteed not to be offset and sealed to reduce dust from entering the servo driver, and the connector port needs to ensure that the surrounding position is sufficient and not offset, so that the encoder, displacement sensor, etc. can be connected to the connector port.

[0026] The multiple through holes 2 on the end cover 1 are respectively matched with the display screen and the connector port, so that the display screen and the connector port can extend out of the through holes 2, so as to be connected with the corresponding components. The through holes 2 are provided with snap-in grooves 3 around them, and snap-in parts 4 matched therewith are provided at the positions of the snap-in grooves 3. The snap-in parts 4 are snap-in with the snap-in grooves 3 and then installed together with the servo drive end cover 1. The snap-in parts 4 limit the display screen and the connector port during the installation process, and when the servo drive end cover 1 is installed, the snap-in parts 4 fix the display screen and the connector port. The snap-in parts 4 include a first snap-in part 5 and a port snap-in part 6. The first snap-in part 5 is matched with the display screen on the servo drive, so that the first snap-in part 5 can limit and fix the display screen during the installation process of the servo drive end cover 1. A plurality of stepped clamping parts 7 are provided on the inner side of the first clamping part 5, and a chamfer is provided between two adjacent stepped clamping parts 7. When there is an error in the position of the display screen on the main and first clamping parts 5 during installation of the servo drive end cover 1, the stepped clamping parts 7 can be used to limit the position, so that the display screen is located at the center position of the first clamping part 5, and a chamfer is provided between two adjacent stepped clamping parts 7, so that the display screen can be limited more conveniently, that is, it will not get stuck during movement, so that the display screen can be moved to the top of the first clamping part 5.

[0027] The port clamping member 6 is clamped with the position of the connector port on the servo drive end cover 1, that is, the port position is limited and fixed. Since the position of the connector port needs to connect the line, etc., a certain space needs to be reserved on the upper part of the connector port to facilitate the installation of the staff, etc. However, the connector port also needs to be limited and fixed, so a clamping section 8 is provided at the bottom of the port clamping member 6, and the function of the clamping section 8 is to limit the connector port. However, there are multiple connector ports. If multiple connector ports are offset, etc., so that the device cannot be clamped normally, it is necessary to manually move the position of the connector port to clamp or move the position. If it still cannot be normally clamped, the servo drive end cover 1 needs to be disassembled and the connector port needs to be recalibrated. Therefore, in order to reduce the occurrence of the above situation. When the port clamping member 6 is clamped to the connector port, if it cannot be installed normally, the port clamping member 6 at the corresponding position is disassembled to manually fine-tune the connector port. If the normal connection cannot be made after the fine adjustment, the port clamping member 6 with the clamping section 8 made of elastic material is selected, that is, the clamping section 8 at the corresponding position of the connector port is compressed. Thus, the port clamping member 6 can limit the connector port. If the connector port still cannot be connected normally, the servo drive end cover 1 needs to be disassembled and the internal circuit board and other related parts need to be reinstalled. Since there is a certain error during the installation of this device, the connector port is offset, but the range of the offset is mostly no more than 1cm. Therefore, when the device cannot be manually adjusted during installation, the port clamping member 6 with the clamping section 8 made of elastic material can be selected for installation. After long-term use, the elastic part of the elastic clamping section 8 will produce aging and other conditions. Therefore, in order to enable the port clamping member 6 to be used for a long time, the clamping section 8 made of elastic material is sleeved on the bottom of the port clamping member 6. The clamping section 8 made of non-elastic material can be integrally manufactured and formed with the port clamping section 8. Circular holes 9 are also provided on the opposite sides of the surface of the port connector 6, so that the port connector 6 can be threadedly connected to the servo drive end cover 1 to prevent the port connector 6 from becoming loose due to continuous plugging and unplugging of the connector port.

[0028] Detailed instructions for use:

[0029] First install the first clamping member 5 and the port clamping member 6 on the servo driver end cover 1, and then connect the servo driver end cover 1 to the servo driver housing. At this time, the first clamping member 5 and the port clamping member 6 are limited with the display screen and the connector port at the corresponding position. Since there will be errors between the display screen and the multiple connector ports during installation, when the connector port cannot be connected, the port clamping member 6 at the corresponding position is first removed, and then continues to be connected to the servo driver housing. After the connection is completed, the connector port is adjusted so that the port clamping member 6 can connect the connector port. If the connection cannot be made normally, replace the clamping section 8 with the port clamping member 6 made of elastic material for connection. After the connection is completed, fix the servo driver end cover 1 to the servo driver housing, and the port clamping member 6 to the servo driver end cover 1.

[0030] In summary, the device enables the servo driver to be fixed in position if there are slight errors in the connector port, display screen, etc. during installation, thereby reducing the need for manual one-to-one correspondence. When there is an error in the connector port, the port clamp 6 at the corresponding position can be disassembled, and then after the overall connection is completed, this place can be processed and installed separately, avoiding the situation where all disassembly and installation are required when one place cannot correspond. In addition, when there is an error in the connector port that cannot be adjusted, the device uses a port clamp 6 with an elastic clamp section 8, thereby reducing the number of times the device is disassembled and adjusted, making the device convenient for subsequent installation.
